Feature: 1. The wireless module of NRF24L01 + power amplifier + LNA is a high-power and high-sensitivity wireless data transmission module specially developed for 1100 meters ultra-long-distance data transmission. 2. NRF24L01P+Power Amplifier+LNA wireless module works in the 2.4G frequency band without license and it can support point-to-point applications can also form a star network. 3. Digital transmission chip NRF24L01+, which adds high-power power amplifier and LNA chip, radio frequency switch, band-pass filter, etc. And they constitute a professional completely bidirectional RF power amplifier, which makes the effective communication distance greatly expanded. 4. In the radio frequency part, a lot of optimization and matching are done to make the transmission efficiency get the highest and the harmonics are the smallest, so that the NRF24L01P + power amplifier+LNA wireless module has the lowest radio frequency interference to external equioments, and it is not susceptible to interference from other equioments, which greatly improves the stability of work. 5. And NRF24L01P+power amplifier+LNA wireless module is highly integrated and easy to embed in any product with space constraints. Customers need to add a microcontroller unit to control NRF24L01P+power amplifier+LNA through serial peripheral interface port. 6. Wireless module can complete the design of the ultra-long-distance wireless data transmission system, and there is no need to worry about the research and development of the RF part, which greatly reduces the research and development funds and shortens the research and development cycle.
